Corrosion of T92 Steels in Na₂SO₄ Salts at 800 and 900°C

Abstract:

The corrosion behavior of the ASTM T92 steel in the Na₂SO₄ salt was studied at 800 and 900°C. At 800°C, the T92 steel formed thin (Fe, Cr)-rich oxide scales, indicating a good corrosion resistance due to 9%Cr presented in the alloy. However, at 900°C, the T92 steel displayed poor corrosion resistance, because the scales dissolved off rapidly owing to the increased corrosion rate.
